SPEC IAL PACKAGE 7 Filed April 2, 1952 all) Patented May 2, 1933 EJNETED STATES Parent caries PAUL ARZET, 0F SHELBYVILLE, INDIANA, ASSIGNOR TOTHE KENNEDY CAP. LINER II' BAG 60., OF S HELBYVILLE, INDIANA, A COBF-UEATION OF INDIANA SPECIAL Application filed April 2,

This invention relates to special packages and particularly to a bag or receptacle for packaging finished laundry.

One of the objects of the invention is to provide a laundry receptacle having a relatively stifi' bottom, flexible sides, and a relatively stiff independent insert in the form of an endless sided member adapted to be folded fiat so that the empty receptacle with the insert inside may be stacked flat in bundles, for shipment.

Another object of the invention is the provision in a laundry receptacle as described, or the insert having re-entrantl folded ends which when folded out against the constraint of the flexible envelope, execute a toggle action past the dead center or the fold, so that the insert is maintained self-expanded, and in turn holds the flexible envelope open so that it can be conveniently packed with the various laundered articles.

Other objects of the invention will apper i as the following description of a pre ferred and practical embodiment thereor' proceeds.

In the drawing which accompanies and forms a part of the following specification, and in which the same characters of reference have been employed throughout the several figures to designate identical parts:

Figure 1 is a perspective view of the lanndry bag or receptacle filled and sealed;

Figure 2 is a transverse vertical section;

Figure 3 is a fragmentary perspective view showing one of the re-entrantly folded ends in partially expanded position in broken lines, and infully expanded position past dead center, in full lines;

Figure l is a perspective view of the receptacle, expanded but still open at the top and with parts broken away to show. otherwise hidden parts; and

Figures 5, 6 and 7 show various stages in the folding of the laundry receptacle reducing it to the flat form in which it is shipped or transported when empty.

Referring now in detail to the several figures, the numeral 1 represents an envelope, the sides and ends of which are preferably of a suitable rade of flexible paper. The

bottom 2 is preferably a rectangular sheet of relatively stitl material, to which the lower marglnsot' the sides and 'ends are at tached as indicated at 3 in Figure 2, by pastbe considered as limiting the scope of the invention.

The envelope 1 is provided with a stiffening insert 4 comprising a strip of relatively still material having a width preferably less than the height of the envelope and formed into an endless band but having its adjacent ends brought together as indicated at 5 in Fig. l, and pasted together by a suitable adhesive strip 6. The endless insert is preferably scored transversely so as to be folda-ble along lines adapted substantially to register with the corners or" the bottom sheet 2, and the ends 6 and 7 of the insert are scored or otherwise constructed so as tobe foldable re-entrantly as is indicated in broken lines in Figure 3. Theinsert is structurally independent of the envelope and may be taken out or folded flat and placed on its side in the envelope against the bottom thereof in order to form a fiat package for shipment.

In the use of the receptacle, the insert is arranged to form sides and ends perpendicular to the bottom 2 and the re-entrantly folded ends are pushed outwardly, thrusting against the sides of the envelope 1 until finally the intermediate foldsof said ends spring past the dead center and assume the full line position shown in Figure 3, in which position they automatically maintain theinsert in open or expanded position, and the insert pressing against the envelope holds it open. The open position of the receptacle is shown in Figure l, and itis obvious that articles of laundry, or for that matter, ar-.

ticles of any nature may be packed in the receptacle;

.Figures 5, 6 and 7 show that the insert'in its folded collapsed state may be laid on the bottom of the envelope, since the height of the insert is not greater than the width of the bottom. The flexible envelope may be folded down in any convenient manner. Figure 5 shows that the middle portion of the envelope is held up-right, the side portions fold- 5 ing fiat and convergent at theends. The upright portion is then laid fiat as shown in Figure 6, and together with the convergent ends is folded back upon the package in the manner indicated at 8. The fiat folded por- 10 tion is then folded in the reverse direction, bringing its free edge over the center of the package as shown at 9 in Figure 7 A number of these fiat units may be bundled together and shipped as one package.

15 While I have in the above description disclosed what I believe to be a preferred and practical embodiment of the invention, it is to be understood that numerous changes in the construction and modification of the re- 2 ceptacle may be made without departing from the spirit or scope of the invention as claimed.

hat I claim is:

1. Special package comprising an en- 2 velope of parallelepipedal shape having a relatively stiff bottom and relative flexible sides, and an endless insert forming a lateral lining for the lower part of said envelope, and folded so as substantially to register 39 with the edges of the bottom, said. insert be ing re-entrantly folded at its ends, said ends when opened within said envelope being adapted to execute a toggle movement against said envelope past dead center,

5 thereby sustaining said insert and said envelope in open position.

2. Special package comprising an en velope of parallelepipedal shape having a relatively stiff bottom and relativelyflex- 5.0 ible sides, and an independent endless insert forming a lateral lining for the lower part of said envelope, and folded so as substantially to register with the edges of the bottom, said insert being re-entrantly fold- .5,. ed at its ends, said ends when opened within said envelope being adapted to execute a toggle movement against said envelope past dead center, thereby sustaining said insert and said envelope in open position.

1 3. Special package comprising an envelope of parallelepipedal shape having a relatively stiff bottom and relatively flexible sides secured to the edges of said bottom as by pasting, and an endless insert forming a lateral lining for the lower part of said envelope, and folded so as substantially to register with the edges of the bottom, said insert being re-entrantly folded at its ends, said ends when opened within said envelope being adapted to execute a toggle movement against said envelope past dead center, thereby sustaining said insert and said envelope in open position.

In testimony whereof I aflix my signature.
